What is a prior authorization?
Last updated September 3, 2026.
Prior authorization is the plan's pre-approval gate: HealthCare.gov defines it as approval required before a service or prescription is covered. Your doctor's office files it, plans must now answer within 72 hours urgent or 7 days standard under CMS's rule, and a denial is appealable. Ask whether a new prescription needs one on day one.

What to do
- Ask at prescription time: does this need prior auth?
- Let the doctor's office file it - and ask them about covered alternatives too.
- Know the clocks: 72 hours urgent, 7 days standard for the big payers.
- Denied? Ask your doctor to appeal - medical-necessity letters flip many.
